Special film for ginger planting

Abstract

The invention provides a special film for ginger planting and belongs to the technical field of agricultural films. The special film is prepared from components in percentage by mass as follows: 15%-20% of white high-pressure recycled plastic particles, 27%-32% of white EVA sticky film recycled plastic particles, 38%-42% of blue high-pressure recycled plastic particles, 8%-13% of blue anti-fog and anti-aging masterbatch and 1%-3% of dark blue masterbatch. The special film for ginger planting is high in mechanical strength and adapts to light transmission for growth and development of ginger, and yield of the ginger can be increased remarkably.

Description

technical field [0001] The invention belongs to the technical field of agricultural films, and relates to a special film for ginger planting, which has low cost, is easy to recycle, and saves time and labor when removing the film. Background technique [0002] Ginger prefers warm temperatures but is not resistant to strong light. Generally, it is cultivated on sloping land and slightly shady plots. However, in order to expand the planting area, film or shed film cultivation is often used. At present, most of the films or shed films used for ginger are black and white films. Studies have shown that black films are more conducive to the growth and development of ginger than white or transparent films. However, the existing black or colored films have the following shortcomings in the actual planting and application of ginger: First, the color of the film is easy to fade with the prolongation of use time, and the growth light environment favorable for the growth of ginger canno...

AI Technical Summary

Problems solved by technology

However, existing black or colored films have the following disadvantages in the actual planting application of ginger: the one is that the color of the film is easy to fade with the prolongation of the service time, and the growth light environment favorable to the growth of ginger cannot be maintained in the later stage; Different chromaticities have different effects on the final yield of ginger. The increase or decrease in the amount of anti-aging masterbatch alone cannot meet the needs of ginger for the quality of transmitted light. Improper selection of color masterbatch will cause a reduction in ginger yield; at the same time After the existing color masterbatch is added to the film material, due to the components, the strength of the film will often be reduced, and the weather resistance will also be reduced, which will seriously affect the production of ginger.

[0003] The formula of existing ginger film basically adopts high-pressure polyethylene plastic particles, high pressure 2426H 30%, linear 7042 60%, metallocene 10%, and the defect of this kind ginger film is that 1. the white film is transparent to direct sunlight, The temperature is too high at noon to roast the seedlings, the leaves are rolled at the dry side, and the insulation effect at night is poor, the temperature drops quickly, the temperature difference is large, and the ginger seedlings grow slowly; ② there is water mist in the film, and the temperature rises slowly in the morning and morning; Water will damage the film and ventilate; ④ Expensive and high cost; ⑤ Time-consuming and labor-intensive to remove the film, difficult to recycle

[0004] At present, there are many types of agricultural plastic films used in production. Although there are various types of product specifications in width and thickness, there is no film or shed film suitable for a certain crop that is produced according to the light-demanding characteristics of the crop.
